Application filed .Tune 3, 1901.

To 61/ whom it may concern.-

Beitknown that I, CHARLES A. LANG, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Paper-Dampening Machines,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to paper-dampening machines; and it consists'of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure 1 is areal end elevation of my improved machine. Fig- 2 is a plan view. Fig. 3 is a view showing one side. Fig. 1 is a view showing the side opposite from that shown in Fig. 3. Fig. 5 is a longitudinal section taken approximately through the center of the machine and showing the arrangement of the different parts. Fig. 6 is an enlarged detail view showing the devices by which the edge of the paper is held upon the surface of the rotary drum. Fig. 7 is a detail view showing the location and arrangement of the shaft, to which is connected one end of a reversible section of absorbent cloth. Fig. 8 is adetail view showing the devices by which the clam ping attachments are operated.

In the construction of my improved machine I provide the end frames 1, which support a table or inclined platform 2, sloping from the front toward the rear of the machine and consisting of two parts, the rear part 3 being hinged, so that it may be raised or lowered to afford access to the mechanism supported below it. A rotary drum 4c is supported between the side frames 1, and the up per surface of said frame is adjacent to the rear edge of the part 3 of the table. A longitudinal groove 5 is formed in the drum 4, and a rod or shaft 6 is carried by the ends of the drum within the said groove 5, and a series of curved fingers 7 are carried at intervals by the said rod6. The said rod 6 is turned when the drum is rotated so that the ends thereof bear upon the surface of the drum, as shown in Fig. 6; but the moment the groove 5 passes beyond the lower edge of the part 3 of the table the said rod is turned to raise the fingers to a vertical position, as shown in Fig. 5. Upon one end of the said rod 6 is a small and a pawl 16.

gear 8. An arm 9, carrying a gear-sector 10,

is pivoted tothe end of the drum ehand a small roller 11 is carried by the inner end of the arm 9 and operates upon the periphery of the cam 12, fixed to the end frame 1. \Vhile the drum is rotating the roller 11 moves over the surface of thecam 12, and thereby operates the arm 9 and the sector 10, which is in mesh with the gear 8, thereby operating the rod 6 to move the fingers 7 into the position shown in Fig.6. The arrangement of this cam 2 is such as to permit the .rod (3 to turnand raise thefingers 7 to avertical position when the said fingers have passed beyond the lower edge'of the part 3 of the table. These fingers are slightly raised to release the edge of the paper to permit the latter to be carried awayfrom the drum by the carrying-ropes, which I will presently describe. The fingers,

however, are not entirely raised to a vertical position till after the fingers have passed beyond the edge of the part 3 of the table.

In the side of the drum 4, opposite from the groove, 5, is formed a second groove 13, in which is carried a rod or shaft 14, held from turning by means of a ratchet-wheel 15 A section 17 of rubber is attached to the rod 14, and the said rubber extends around the surface of the drum to the groove 5, where it maybe attached to the pins or projections 18, carried within the said groove 5.

19 indicates a rod which is supported by the frames above the drum 4, and a number of arms 20 are carried by the said rod 19, the said arms 20 being bent into suitable shape and having their ends terminating adjacent to the surface of the drum 4, thereby forming stops orgages for the paper as it is fed from the table to the drum and holding the paper until the fingers 7 have been operated to bear upon the paper in order to hold it while the drum is rotating. A number of curved arms 21 are supported at the rear side of the drum 1 and form guides to hold the free end of the paper in position while it is being carried around by the drum.

22 indicates a trough or basin adapted to contain water and supported below the drum 4, the lower side of the drum extending into the said trough or basin, so that it will become dampened when rotated. A roller 23 is supported by the frames 1 within the trough -or basin 22 and upholds the free end of the paper after it has passed beyond the ends of the arms '21. the front side of the trough or basi-n'22 and serves to remove the excess water or moisture from the paper as it is carried upwardly-out of the said trough or basin by the drum. A shaft 25 is supported by the side frames 1 above the roller 24, and a similar shaft 26 is' supported by the said side frames below and in front of the said shaft 25. sheaves or pulleys 27 are carried on each of the shafts 25 and and ropes or belts 28 are passed around the said sheaves or pulleys.

- A power-shaft 29 is supported at one side of the machine, to be driven by belts applied a rope or belt 35 passes around the said sheave or pulley and around a pulley 36, carried by the end of the shaft 25, thereby rotating the said shaft and moving the ropes or belts 28. A roller 37 is supported by the side frames 1 above the shaft 25 and rests upon the sur- 4 face of the drum 4 and serves to remove all frames 1, and a spring-held excess moisture.

A' transverse rod 38 is supported by the pulley 39 is supported by the said rod 38, and a belt or rope '"40 passes around the said pulley 39 and around the drum 4, as shown inFig. 5, and the said belt or rope serves to guide the upper edge'of the paper over the pulleys 27 onto the belts or ropes 28, whereby the paper will be carried downwardly and placed upon a number of arms, by means of which it is delivered to an adjacent platform.

A rod or shaft 41 is supported in front of the shaft 26, and a series of arms 42 are fixed upon the said shaft, and the said arms extend upwardly at an incline, their upper ends resting between the rods 28. A gear-wheel 43 is fixed to the end of the shaft 41, and a rack 44 is in mesh with the gear 43, said rack being fixed to the end of an arm 45, and the said arm is pivoted to the frame 1. An arm 46 is pivoted to the frame 1 above the arm 45 and is connected to the said arm 45 by a rod 47. The rear end of the arm 46 carries a small roller 48, which rides upon the cam 49, the latter being fixed to one of the trunnions of the drum 4 and turning as the said drum rotates. By this means the rear end of the arm 45 will be raised once during each revolution of the drum 4, which will operate the arm 45 and the rack 44 and rotate the shaft 41 and operate the arms 42 to raise the paper from the ropes or belts 28 and deliver the same onto an adjacent platform 50. The

A roller 24 is supported above.

A number of stops or gages 20 are raised at the requiredv time to permit the paper to pass by means of delivered onto the table 2 and passed rearv. wardly until the lower edge thereof engages against the stops or gages 20. The drum 4in -the meantime-is rotating, and the fingers 7 will be operated by the rack 10 to clamp upon l the edge of the paper and hold the same on the drum while thelatter is rotating; The

stops 20 are now raised bythe arm 51, which is operated bythe cam 52 to permit the paper to pass. The paper is carried around by the drum and is passed through thewater in the trough or basin 22, whereby it:will be dampened. The free edge of the paperwill be The paper will be carried-upwardly out of the trough or basin 22, and excess waterand moisture will be removed therefrom by the roller 24. When the fingers 7-have passed above the sheaves or pulleys 27 on the shaft 25, they permit the paper to passtherefrom A upheld by the. arms 21 and by the roller 23.

and be guidedoutwardly by the rope or belt 40 and delivered onto theropes or belts 28, whereby it will be carried downwardly above the arms 42. The arm 49 now raises the rear end of the arm 46, which also operates the arm 45 and rotates the shaft 41. This raises the arms 42, which remove the paper from the ropes 28 and deliver the same onto the platform 50. Thus it is seen that one sheet of paper is moistened by each revolution of the drum 4 and is also delivered from the drum onto the platform, from which it may be removed to any suitable place.

I claim- 1. A machine for dampening paper, consisting of adrum, aliquid-receptacle located below the drum, means for rotating the drum, means for holding the paper upon the drum so that it will be carried around therewith and passed through the liquid-receptacle when the drum is rotated, and means for antomatically releasing the paper from the drum, substantially as specified.
